"I've had the pleasure of working with Precious as part of the Integration Monitoring team at checkout.com, where he worked as our front-end engineering expert. From the start, Precious has consistently impressed me with his technical expertise, creativity, and dedication. He built the first version of our UI entirely from scratch, a task that required not only strong coding skills but also a deep understanding of user experience and design principles. Precious is a proactive problem-solver, always eager to take on challenges and push boundaries to deliver high-quality results. His ability to balance both the technical and aesthetic aspects of front-end development has been key to the success of our project. Beyond his technical skills, Precious is a great team player—collaborative, communicative, and always willing to share his knowledge with others. I highly recommend Precious for any future roles, as I am confident he will continue to excel and bring value to any team lucky enough to have him."

Like micro-services for APIs, the micro-frontend architecture is a front-end web development pattern in which a single application may be built from different builds. It enables independent development, deployment, and scalability of individual frontend modules using different frameworks if needed. Micro-frontends can break down the front end into smaller, self-contained modules that can be developed, tested, and deployed independently.
As companies strive to deliver exceptional user experiences and navigate the evolving landscape of web technologies, the role of a senior frontend engineer has become increasingly critical. Senior frontend engineers are experienced professionals who possess a deep understanding of frontend development and play a crucial role in shaping the technical direction of projects.

This can be achieved by putting automated checks in place at various steps, this checks can be unit tests, integration tests, end-to-end tests, a build step and more. This process is known as Continuous Integration and Continuous Deployment (CI/CD).
